The present disclosure relates to a method and apparatus for performing a dry plasma procedure, while mitigating internal contamination of a semiconductor substrate. In some embodiments, the apparatus includes a semiconductor processing tool having a dry process stage with one or more dry process elements that perform a dry plasma procedure on a semiconductor substrate received from an input port. A wafer transport system transports the semiconductor substrates from the dry process stage to a wet cleaning stage located downstream of the dry process stage. The wet cleaning stage has one or more wet cleaning elements that perform a wet cleaning procedure to remove contaminants from a surface of the semiconductor substrates before the semiconductor substrate is provided to an output port, thereby improving wafer manufacturing quality.

Integrated platform for improved wafer manufacturing quality

A method of cleaning a substrate such as semiconductor substrate for IC fabrication is described that includes cleaning the semiconductor substrate with a mixture of ozone and one of an acid and a base. Exemplary acids and bases include HCl, HF, and NHOH. The cleaning mixture may further include de-ionized water. In an embodiment, the mixture is sprayed onto a heated substrate surface.
